Water flows into a tank for 24 hours. R(t) represents the gallons of water in the tank at t hours. What does R'(t) represent? Check all that apply.

• the amount of water in the tank in gallons

• the rate of change of the water at t hours

• the speed of the water flow at t hours

• gallons per hour

Is the above function differentiable for all values of x? Why?

• Yes, the slope of the tangent line can be calculated for all values of x.

• Yes, the function is continuous for all values of x so the function is differentiable.

• No, the function has a sharp turn in the first quadrant so if is not differentiable.

• No, the function is discontinuous so it is not differentiable.

In which quadrant of the graph above will there be a value of x that is non-differentiable?

• 1

• 2

• 3

• 4

Is the above function differentiable at

x = 0? Why?

• Yes. The derivative would be equal to zero since there is a vertical tangent.

• No. The derivative would not exist at x = 0 since there is a vertical tangent.
